Title: Combustion equipment of direct injection type diesel engine
Inventor: MORI SHUNICHI
IPC: F02M63/00
Filed: 1989-02-28
Abstract: PURPOSE:To make it possible to restrain sudden combustion at the initial stage of combustion and expedite the dispersion at both middle and later stage of combustion by arranging an injection valve with four injection ports in such a way that its horizontal injection is directed to a sidewall in the minor axis of a combustion chamber. CONSTITUTION:Each of combustion chambers 1a and 1b installed on the top of a piston 1 takes the shape of a cocoon, namely the horizontal section of chamber is round and its part is overlapped on a part of the other chamber in the vicinity of the middle of the piston 1. On the other hand, a fuel injection valve 3 installed to a cylinder head 2 is arranged at the upper middle part of the cocoon-shaped combustion chambers 1a and 1b, and horizontal, fuel injection angles theta1 and theta2 are set as theta2>theta1, so that the injected fuel collides with the wall surfaces 1c to 1f of the combustion chambers in the minor axis 'y' direction of the cocoon-shaped combustion chambers 1a and 1b. With this contrivance, sudden combustion in the initial stage of combustion can be restrained, while an exhaust quantity of nitrogen oxides, generated remarkably in the initial stage, can be lessened. In addition, in the middle and later stage of combustion, mixing of fuel and air is improved to expedite combustion and consequently generation of black smoke is suppressed, while fuel consumption is improved.

IPC: B41J29/00
Filed: 1990-02-28
Abstract: PURPOSE:To prevent capacity coupling between hands of man and the like without necessitating any special countermeasure such as the provision of a shield plate and the like by a method wherein an operating panel board is provided in a casing so that the panel board is separated from an operating unit with a distance, in which capacity coupling will never be caused between the hands of man near the operating unit. CONSTITUTION:An operating panel 12 is constituted of an indicating member, an operating unit 13 equipped with push buttoms and the like and an operating panel board 14, separated from and opposed to the operating unit 13. The operating unit 13 is arranged on the surface of the casing body 15 of a printer device 11. The operating panel board 14 is arranged at the bottom of the casing body 15 and is separated from the operating unit 13 sufficiently. The operating panel board 14 is separated from the operating unit 13 sufficiently (in the degree of several ten-several hundred mm). Generally, when the operating panel board is separated from the operating unit by 20-30mm, capacity coupling between the operating panel board is not caused when hands are approximated to the operating unit. Accordingly, the capacity coupling can be eliminated and reliability can be improved in this operating panel 12 and, further, any shielding plate is not necessitated to be added.

Title: Blade for cutting glass
Inventor: ICHIKAWA HAJIME
IPC: C03B21/02
Filed: 1990-02-27
Abstract: PURPOSE:To obtain the subject blade free from early generation of chipping even at a low shape precision and having increased cutting frequency to enable good cutting operation by mixing Cr oxide and Al oxide in dispersed state into an Fe-based alloy containing Fe, Ni and Co. CONSTITUTION:The objective glass cutting blade is produced by mixing Cr oxide and Al oxide in dispersed state in an Fe-based alloy containing 50-60wt.% of Fe, 25-35wt.% of Ni and 10-20wt.% of Co. The seizure of the blade to the glass can be suppressed and the profile irregularity of the glass can be improved by mixing Cr and Al oxides in dispersed state in the Fe-based alloy. The blade is resistant to deformation because the linear expansion coefficient of the Fe- based alloy is comparable to that of glass at >=800 deg.C [i.e., (5-6)X10<-4>deg<-1>] and the lowering of the mechanical strength at a high temperature can be suppressed because of high oxidation resistance of the alloy. Since the edge is made of an Fe-based alloy, it has electrical conductivity and can be worked to a complicate and sharp shape by electric discharge machining.

Title: Electrophotographic sensitive body
Inventor: SUMINO FUMIO
IPC: G03G5/14
Filed: 1987-03-03
Abstract: PURPOSE:To suppress the raise of potential in the light by using a polymer having nicotinic acid amide derivatives as oxidation reduction pendants for an underlayer. CONSTITUTION:The polymers having nicotinic acid amide derivatives as the pendants are known as the oxidation reduction type polymer having reversible oxidation reduction reactivity. In corporation of such a polymer in an underlayer between a substrate and a photosensitive layer permits electrons generated in the photosensitive layer to easily escape to the side of the substrate. The nicotinic acid amide pendant is added along or in a mixture with other materials generally in an amount of 20-50wt.% of the underlayer, when the pendant polymer is used alone or mixed with other materials, and the upper limit is restricted by the compatibility of said amide derivative with the polymer and the film forming performance of the polymer to be formed, thus permitting the raise of potential in the light variance of potential in the dark to be restrained even during repeated uses.

Filed: 1991-03-12
Abstract: PURPOSE:To prevent deterioration in picture quality due to residual toner by providing an exposure means which exposes a photosensitive body to a white paper pattern or a pattern close to white paper every time a previously set specific print quantity is counted. CONSTITUTION:A CPU 21 checks whether or not the print quantity N counted by a specific pattern printing start counter 25 reaches the previously set quantity Ni once printing start operation is performed. When not, the print quantity N counted by the counter 25 is increased by one after one-page printing. When N=Ni, the white paper pattern or pattern close to white paper is read out of a specific pattern print data ROM 24 and white paper printing is performed. In this white paper printing, residual toner on the photosensitive body is removed. At this time, half-tone characters 'Cleaning printing is in process now' are printed and an operator confirms the completion of the white paper printing.

Abstract: PURPOSE:To avoid the change-over operation of an unnecessary column or the wasteful consumption of a sample at the time of re-analysis, by mounting a command execution necessary/unnecessary memory means and executing only a necessary command with reference to said memory means at the time of actual analysis or re-analysis. CONSTITUTION:In the case of actual analysis when analytical processing is carried out, on reference to the actual analytical data of a practice judge table memory region 7a, a command is executed at the time of 1 and said command is skipped at the time of 0 to transfer to the next command. At the time of re-analysis, the file name thereof is designated by a keyboard 6 and the required wave form data in a wave form memory 8a is read and, on the basis of the value thereof, wave form processing and the recording of a chromatogram are performed. In this case, an interpreter program carries out a time program at a high speed in matching relation to the high speed elapse of a time at the time of re-analysis and the re-analysis necessary/ unnecessary memory of the region is referred to in the execution of each command and said command is executed at the time of 1 but skipped at the time of 0 to transfer to the next command. Therefore, the unnecessary change-over of a column can be avoided and the wasteful consumption of a sample can be prevented.
